Creating a real-time chat application using WebSocket in Python not only helps you understand how WebSocket works, but also provides a direct communication experience among users. Here's a basic guide to get you started:
Install the WebSocket Library
websockets library to create WebSocket server and client. You can install this library using pip:
pip install websockets
Build the WebSocket Server
import asyncio import websockets async def handle_client(websocket, path): async for message in websocket: # Handle messages from the client # Send the message back to all connected clients await asyncio.wait([client.send(message) for client in clients]) start_server = websockets.serve(handle_client, "localhost", 8765) asyncio.get_event_loop().run_until_complete(start_server) asyncio.get_event_loop().run_forever()
Build the WebSocket Client
import asyncio import websockets async def receive_message(): async with websockets.connect("ws://localhost:8765") as websocket: while True: message = await websocket.recv() print("Received message:", message) asyncio.get_event_loop().run_until_complete(receive_message())
Run the Application
Open two command line windows, one for the WebSocket server and one for the WebSocket client. Run the server code first, then run the client code. You will see real-time messages being sent and received between the two windows.
Customize and Enhance
From here, you can customize and enhance your application by adding features such as user authentication, data encryption, chat history storage, and more.
Building a real-time chat application using WebSocket in Python is a great way to learn how WebSocket works and experience real-time communication among users.
